CARBURETER.

reference marked thereon, which form a part of this specification.

This invention relates to improvements 1n carbureters for, use in connection with explosive engines, and, while especially adapted for use in connection with these engines where employed in connection with automobiles, it is evident that'the carburetor is equally valuable wherever engines or motors of this character are employed.

' y object is to obtain a more intimate mixture of the gasolene and the air, where by a better explosive mixture is formed thanwhere the old forms of carbureters are employed. i v

r An important feature of my improved introducing the v with :air under construction consists in gasolene mixture mingled pressure, and, at the same the gasolene to an atomizing operation by the introduction of the air under pressure, the atomizing'apparatus beingsuitably connected with the receiver of! an air compressor, which may be mounted on the automobile or suitably located where the engine is of the stationary form. Provision is made for automatically feeding'the liquid gasolene to the automizingdevice simultaneously with the introduction of 'the airunder pressure. Above the atomizer is a relatively large chamber into which :the explosive mixture is delivered, this chamher being in communication with the engine, whereby it may be sup iied to the cylinders under pressure supp emented by suction resulting from the action of the cylinder pistons. In the usual form of construction, the explosive mixture is acted on by the suction within the cylinders-only, while in my improved form of construction, this suction is supplemented by the pressure of the air within the mixing chamber.

Provision is made for introducing air to the carburetor other than that delivered to the atomlzing nozzle from the receiver of the air compressor. This auxiliary air may be regulate as circumstances may require, by the adjustment of an inner cylinder, which is provided with a flange equipped with elongated openings. arranged to register with'perforations formedin an adjacent fiangeofthe outer casing. By impart-.

ing-a partial rotary movement to the inner cylinder, maybe 'partly-or-entirely cut off, as may be Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof. In this drawing: Figure is a central vertical section, taken through my improved carbureter'. Fig. 2 is a side elevation of the same. Fig. izing nozzle,

taken on the linen-5 of Fig. 1. The same reference characters indicate the same parts in all the views.

Let the numeral ing which is effect at the top shown at 6 and 7 the oflset provided with" perforations 8 arranged to register with elongated openings 9 formed in an adjacent flange 10 of an inner cylinder ich -is'*connected with a top plate 13 and bottom, as

forming a communication between the inner cylinder and an outer chamber 16 formed between the upper portion of the inner cylinder and the outer casing. The top plate :13 of the. innercylinder is provided with a wrist pin 17 to which is secured acrank 18, which is employed for manually adjusting theinner cylinder for the purpose of regulating the supply of air through the openings-8 and 9. The outer casing is closed above the top plate 13- of the inner cylinder by a plate 1-9, which rests upon an 'in'te- 'riorly-projecting flange 20 of the said casing. Theolfset portion 6 of the'outer casing is provided interiorly with an upwardly-projecting member 21 which is interposed between the chamber of the inner cylinder and perforations 22 formed in the upper portion of the outer casing. These perforations 22 are for the admission of an additional supply of air, if the same shall the admission of the auxiliary air 5 designate an outer cas= portion 7 being 7 3 1s a cross section of the atomthat the perforations as may be found desirable, By interposing I the wall 21 between upper extremities It must be understood 22 are not vital to the invention, as the apparatus may be employed with or without these perforations,

the chamber of the inner cylinder and the perforations 22, the air is compelled to pass upwardly over the member '21 and then. downwardly into the chamber 23 of the inner cylinder, thus compelling the air so introduced to become in ,timately mixed with the gasolene mixture before passing to the engine through the outlet opening-24. When the inner cylinder 12 is adjusted, as illustrated in Fig. 1, of the drawing, an opening 25 formed in the said cylinder just registers with the opening 24 formed in a neck 26 of the outer casing. When, howeveigthe cylinder 12 is rotatably adjusted for the purpose of regulating the supply of air through the openings 8 and 9, the relatively large opening 24 is partially cut off, but the inner cylinder is provided with an auxiliary slot or opening 27 to compensate to a certain extent for the cut-01f resutling from such rotary action. It is intended, by virtue of this construction and arrangement, to regulate the outlet opening to the engine t harmonize with the regulation of the air inlet openings 8 and 9.

Thelower offset cylindrical portion 28 of the outer casing is interiorly threaded at its lower extremity, as shown at 29, whereby it is connected with the exteriorly threaded 1 upperpart 30 of a receptacle 31 for gasolene 32, which is .admitted through a passage 33 formed in a nozzle 34 fitted into an opening 35 formed in the lower part of the said receptacle. The passage 33 is controlled by a valve 36 providedwith a stem 37, in which is formed a recess 38 into which projects the T-shaped extremity 39 of a lever 40, which is fulcrumed at 41, the fulcrum pin having its extremities fast in the walls of the receptacle 31 and passing through a hub 42 of the lever. The long arm of this lever is bifurcated forming arms 44 which extend to the opposite sides of a ring 45, the ring being provided with pivot pins, which pass through openings formed in the extremities of the lever arms 44, whereby the lever is pivotally connected with the said ring. Thls ring is equipped with upwardly-projecting lugs 47, whose are. riveted to angled brackets 48 secured to the bottom of a float 49 mounted in the gasolene receptacle and arranged to act upon the lever, whereby the latter is caused to open and close the valve 36, according as the gasolenc falls and rises in the said receptacle. Directly above the op'eniug35. into which the inletnozzle 34 is screwed, is located a threaded opening 50 into which is screwed a plug 51 having an -.7 opening 52 adapted to receive the upper extremity of the valve stem 37 whereby the valve is accurately guided during its rise and fall in response to the action of the lever 40.

The bottom of the receptacle 31 is provided with a depending nipple 53 in which is formed an air inlet opening 54. This nipple may be connected in any suitable manner with a source of compressed air, not shown. Above the passage 54, the bottom of the receptacle 31 is reinforced and counterbored to form a threaded socket 55 into which is screwed the lower exteriorlythreaded extremity 56 of a tube 57 forming apart of an atomizer. This tube passes upwardly througha central opening 58 formed inthe float 49, 1138' upper extremity being equipped with a leeve 59, which is vertically slidable thereon and into which is brazed a disk 60 having a depending threaded part 61 screwed into the top of the tube 57, the said disk being provided with a central opening 62, the disk being counterbored below said opening to-form a somewhat larger opening 63- for the passage of air around a relatively small inner tube 64 passing centrally through the air tube 57, its upper extremity being contracted as shown at 65, whereby a space is left around the upper portion of the inner tube for the 9 escape of air which enters the tube 57 from the inlet passage 54, the lower part of the inner tube 64 being formed spider-shaped and fitted into the lower part of the tube 57,

The opening 70 is made slightly larger than the sleeve 59. WVith this exception, the gasolene receptacle is closed at the top. The lower extremity of the inner cylinder 12 is contracted and terminates in a coneshaped part 71, which surrounds the upper extremity of the sleeve 59. The opening,however, in the lower depending cone 12 shaped part 71 of the inner cylinder, is relatively large, leaving ample space for the passage of air from the chamber 72, formed by the lower part of the outer casing. upwardly into the chamber 23 from which the 5 explosive mixture passes to the engine through the registering openings 24 and 25, as heretofore explained. By virtue of this depending cone-shaped cylinder extremity 71, the air entering through the openings 8 nieaeae and 9 is compelled to pass downwardly into through the depending cone-shaped lower the chamber 72, and thence upwardly extremity of the inner cylinder, thus furas around the upper extremity of the sleeve 59, nishing, if necessary, air in addition to that through which the gasolene vapor passes. introduced under pressure through the tube By virtue of this construction and arrange- 57 of the atomizing apparatus.
